Answered 2022-Jan-05 at 14:53Its not a breaking error, just means that some functionalities might not work as expected.
As this npm WARN EBADENGINE required: { node: '>=0.8 <=9' } line shows, the required node version for this package to work as intended is between 0.8 and 9 but you have node 16.

Answered 2021-May-18 at 10:24Try to use unicode expression [ \u0029 = )] with regex

I think your second approach is more appropriate if you have multiple routes having the same issue. If there is only one route, then you can use the above solution.

QUESTION
"npm list" returns this, in which there are no "unmet"s. But when I restart my server, it errors out and the error logs show "Error: Cannot find module 'async/each'" and other similar errors. I have been going through and installing each unfound module individually, but that is very tedious. What should I be doing instead?
EDIT: Also, doing "npm prune" doesn't seem to do anything ("npm list" still gives a lot of ERR-extraneous type things.)
EDIT 2: It's not a very sophisticated server, it's just meant to serve an HTML file and connect to a MongoDB. So the basic dependencies are Express, Socket.io, and MongoDB.

Answered 2020-Oct-08 at 19:27To solve this, I deleted the "node_modules" folder in my build folder, did "npm install [module] --save" for each of the packages found in require statements in my server.js file, wiped my server clean and resynced my build files to it, then did "npm install" on the server.
QUESTION
Path: /1,2,3,456,678 - only numbers and commas, not anything else
Should be matched with regex-like path like this: /ids:(\\d+[,\\d]*) natively
But https://www.npmjs.com/package/path-to-regexp in express compiles it to some ridiculous regex
Expressers/noders - pls guide me how to approach this right
ANSWER
Answered 2020-Oct-05 at 18:22Replacing * with {0,} solved the issue
So request /1,2,34,56 matched by path: /ids:(\\d+[,\\d]{,*})
